Frequented by Pablo Picasso, who had a studio nearby, in 1914, when the English painter Nina Hamnett arrived in Montparnasse, on her first evening the smiling man at the next table at La Rotonde graciously introduced himself as "Modigliani, painter and Jew". They became good friends, Hamnett later recounting how she once borrowed a jersey and corduroy trousers from Amedeo Modigliani, then went to La Rotonde and danced in the street all night.

During this creative era, proprietor Libion allowed starving artists to sit in his café for hours, nursing a ten-centime cup of coffee and looked the other way when they broke the ends from a baguette in the bread basket. If an impoverished painter couldn't pay their bill, Libion would often accept a drawing, holding it until the artist could pay. As such, there were times when the café's walls were littered with a collection of artworks, that today would make the curators of the world's greatest museums drool with envy.[1]

Unlike many establishments in Montparnasse, La Rotonde has retained much of its bohemian charm and continues in operation to this day as a popular spot for the Parisian Intelligentsia.
